MODE 0F CONSTRUCTING PADD'LE-NHEELS FOB. PROPE-LLING- BOATS, 6m.

Specification of Letters Patent No. 360, dated August 18, 1887'.

To all whom t may concern Be it known that I, oHN JAMES GREEN- oUGH, ofBoston, in the county of Suffolk and State of Massachusetts, haveinvented a new and useful Improvement in the waterwheel called fGreenoughs Vertical-Bucket Water-Wheelf which is described as follows,reference being had to the annexed drawings of the same, making part ofthis specification.

This water wheel consists of an axle, arms, buckets with cranks; balanceor guide wheels; latch-bolts for bracing the buckets in their properposition; with lifters and followers for raising the latch-bolt andreturning it to its place again; and friction wheels to confine theguide wheels in their place.

The improvement here claimed is the manner in which the buckets are keptparallel, and, either vertical or at any angle deemed most eflicaciousfor propelling. First, the axle L, Fig. 1 is made of cast or wroughtiron of the usual form. It runs on plumber blocks C, cast with arms tosupport the friction wheel. Second, the arms K are made and braced likethose of the common water wheel; on the end of the arm is an iron braceor strap to admit the bucket pin N, Fig. 1, to be attached to the arm.There is also an iron lifter F, Fig. 3, attached to each arm and afollower G to l'ift the latch bolt E, Fig. l, and follow it back again.Third, the buckets H, Figs. 1 and 4 are made of plank with two stoutbraces M, at its back, one at each end with a piece of plank O runningthrough the center; having also a cross brace Q running over the plankhorizontally, in the center with an iron T brace M; the iron beingbrought to the front of the bucket to keep it steady; the pin N isattached at the front.` These buckets are swung at the center by pins Nturning in the irons on the arms. There are cranks D, Fig. 1, attachedto the bucket pins, having oblong holes P in` them for the latch boltsto shut in. Fourth, the balance or guide wheels A A Fig. 1 for keepingthe buckets in their proper position by means of the cranks areconstructed, with holes in the rim to receive the pins R of the cranks.Aa, Aa, connected by arms or spokes S, working into friction wheels B,Fig. l, grooved on the periphery to hold the balance wheelsjdown intheir proper position; the smaller rims must be made large enough toclear theaxle L at top, by which there can be two guide wheelsattachedwithout interfering with the straight axle L. Fifth, the liftersF and followers GVFig. 3, for lifting the latch bolt E at the top of thewheel and following it back are attached to the arms K. Sixth, the latchbolt E. is fastened to the bottom of the bucket and shuts into the holeP in the crank; its useis to take the twisting strain from the bucketpm.

Operation: While the wheel revolves the buckets are kept in theirposition by means of the cranks D attached to the rim of the balance orguide wheels A these guideV wheelsV being held in their position by thesmall rims Aa working into the groove on the periphery of the frictionwheels B which are attached to the arms of the plumber blocks; the latchbolts E are lifted when the buckets are nearly at the top of the wheelIn the center are smaller rims Y by means of the lifters F; and whenthey have passed the arm they are pressed into place again by thefollowers G.

What I claim as my invention and desirev to secure by Letters Patentconsists in The arrangement and adaptation of the Y parts of the beforedescribed water wheel :A

to wit, the application of the arms to the plumber block described insec. 1; the application of the friction wheel described in sec. 4L; theform of the guide Wheel with the center rim in the same described insec. A; the form of the cranks with the holes P, in the same, applied asdescribed in sec. 3;

the use and application of the lifters and' followers (see section 5)the manner of bracing the buckets, section 3 and the latchbolts section6.
